采用4 × 4拉丁方设计试验，评价了两种全混合日粮（TMR）青贮与食品副产物的适用性。以马铃薯废、酱油饼、豆腐渣、面条废等4种食品副产品为原料，与商业浓缩物（CC）混合作为TMR青贮饲料。T1和T2两种TMR青贮均含有CC，除T1的所有副产物（TRE1）外，T2的酱油饼和面条废料（TRE2）以干物质（DM）为基础。青贮料发酵良好，pH值低，乳酸浓度高。作为试验处理，T1、T2和CC （CTL）饲喂基础饲粮。结果表明：T1组的干物质和有机质消化率高于CC组（P < 0.05），粗蛋白质消化率在T1、T2和CC组间差异不显著（P < 0.05），氮残留不受食物副产物的影响。与CTL相比，TRE1和TRE2的瘤胃pH值立即降低。该研究表明，这两种类型的TMR青贮，包括食品副产品，可以作为商业浓缩物的替代品。
Four wethers were used in a 4 × 4 Latin square design experiment to evaluate the applicability of two types of total mixed ration (TMR) silage with food by-products. Four food by-products (i.e., potato waste, soy sauce cake, soybean curd residue and noodle waste) were obtained and mixed with commercial concentrate (CC) as TMR silage. The two types of TMR silage, T1 and T2, each contained CC, in addition to all by-products for T1 (TRE1), and soy sauce cake and noodle waste for T2 (TRE2) on a dry matter (DM) basis. The silage was well-fermented with low pH values and high lactic acid concentration. As the experimental treatments, T1, T2 and CC (CTL) were fed with a basal diet. The result showed that the digestibility of DM and organic matter (OM) were higher for T1 than for CC (P < 0.05), while crude protein digestibility was not significantly different among T1, T2 and CC. The retained nitrogen was not affected by inclusion of food by-products. Ruminal pH in TRE1 and TRE2 immediately decreased compared to that in CTL. The study suggested that the two types of TMR silage, including food by-products, might be used as a substitute for commercial concentrate.
